ENDURA OVERVIEW

Endura is a high-quality, high-performance network-based video security system, which is based on a powerful distributed system architecture

and hardware/software platform for the total utilization of today’s Ethernet networks. This noncentralized system allows customers to make use

of a facility’s network and network infrastructure, representing a signiﬁcant savings in cabling, hardware, and manpower resources.

No longer limited by traditional, centralized approaches, Endura offers an unconstrained platform for designing and implementing video security

systems. There is virtually no end to how a system and its components can interact and share video, audio, and control information.

The Endura hardware platform offers all the components necessary for designing, installing, and utilizing complete networked digital video

systems. With encoders, decoders, network video recorders, PC workstations, video console displays, storage expansion boxes, and advanced

management technologies, customers now have all the tools necessary for building a high-performance video security system—all delivered

over an Ethernet network with total access ﬂexibility.

ENDURA COMPONENTS

Endura components take full advantage of leading edge technologies such as Universal Plug and Play (UPnP^™), allowing for fast, error-proof

installations and set up. Essentially, when an Endura device is added to a system, it announces itself and the services it has available.

The existing devices acknowledge the new unit and then begin exchanging information as user preferences and proﬁles dictate.

Table A lists the Endura components. Information in this table is updated periodically and might not describe the latest Endura products.

Table A. Endura Components

Endura Component

Description

NET5301T encoder

The NET5301T encoder is a high-performance MPEG4 video encoder. It accepts analog video and audio

signals and converts them into digital TCP/IP packets, as well as provides an interface for relays and

alarms.

NET5301R decoder

The NET5301R is a high-performance video decoder. It converts digital video and audio streams back

into video output for viewing on a composite, S-Video, or VGA monitor.

WS5050 workstation

The WS5050 Endura workstation (WS) is a Windows^®-compatible system that is used for viewing video

and conﬁguring an Endura system. The WS5050 is supplied with all PC hardware in a stand-alone box.

VCD5000 video console display

The VCD5000 video console display (VCD) is a high-performance, multiple-stream decoding unit. It

converts multiple digital MPEG4 streams into video signals to be viewed on either composite, S-Video,

or VGA monitors. Up to four decoding cards can be added to this unit. Four models are available that

allow users to tailor their viewing systems with up to 64 displays. An unlimited number of video

console displays (VCDs) and decoders can be controlled from a single VCD. Using an Endura keyboard

or a standard USB-compatible PC mouse and keyboard, users can access the on-screen menus and

control an Endura system.

SM5000 system manager

The SM5000 system manager (SM) is an integrated hardware/software component that provides

distributed administration of multiple devices. The SM5000 also manages system security, functioning

as a key server for user and device authentication.

NVR5100 Series network video recorder

The NVR5100 Series network video recorder (NVR) represents a whole new generation of ﬂexibility and

integration for network-based video system recording. It sits at the center of Endura, Pelco’s most

advanced integrated video security system. The NVR represents the state of the art in scalability,

features, and reliability.

The NVR5100 is capable of continuous, scheduled, alarm/event, and motion recording. Pre- and post-

alarm, event, and motion recording is also available and is fully programmable on a per-channel basis.

The unit maximizes storage efﬁciency using EnduraStor^™, a time- and priority-based system that

identiﬁes data to be removed when storage reaches capacity.

SEB5000 storage expansion box

EnduraStor storage optimization

The SEB5000 storage expansion box (SEB) is a high-performance storage solution. Each SEB box can

add up to 3.9 TB of network storage. Multiple SEBs can be attached to a single NVR unit, providing a

very large, very scalable network storage solution.

EnduraStor offers the ability to reduce the frame rate of previously recorded video on an Endura system

after a speciﬁed period of time. After captured video has reached a user-deﬁned age, EnduraStor goes

to work to “prune” the database and reduce the number of recorded frames. By enabling EnduraStor

within the system, a user has the unique ability to dramatically extend recording duration at a lower

frame rate.

requirement:

•

Routing Information Protocol (RIP): RIP is a simple routing protocol that is part of the Transmission Control Protocol/Internet Protocol

(TCP/IP) protocol suite. It determines a route based on the smallest hop count between source and destination. RIP is a distance vector

protocol that routinely broadcasts routing information to its neighboring routers and is known to waste bandwidth. It also has a limit of

15 hops. If a route is advertised as having 16 hops, it is ﬂagged as unreachable.

Open Shortest Path First (OSPF): OSPF is a routing protocol that determines the best path for routing IP trafﬁc over a TCP/IP network

based on distance between nodes and several quality parameters. OSPF is an interior gateway protocol (IGP), which is designed to work

within an autonomous system. It is also a link state protocol that provides less router-to-router update trafﬁc than the RIP protocol (distance

vector protocol) that it was designed to replace.

Static routing: This protocol forwards data in a network via a ﬁxed path. Static routing cannot adjust to changing line conditions as can

dynamic routing.

MULTICAST ROUTING PROTOCOLS

Multicast routing is required to allow Endura components to communicate with one another. At least one of the protocols listed below can be

used to meet this requirement:

•

Protocol Independent Multicast (PIM): PIM is a multicast routing protocol that is used in conjunction with an existing unicast routing

protocol. PIM comes in two versions: Dense Mode (PIM-DM) and Sparse Mode (PIM-SM).

–

Dense mode is most useful in the following instances:

•

Senders and receivers are in close proximity to one another.

There are a few senders and many receivers.

The multicast trafﬁc volume is high. Dense mode forwards multicast data everywhere, and lets switches prune out trafﬁc that is

not requested.

•

Multicast data is periodically ﬂooded everywhere.

The multicast trafﬁc stream is constant.

PIM-DM uses Reverse Path Forwarding and looks a lot like Distance Vector Multicast Routing Protocol (DVMRP). The most signiﬁcant

difference between DVMRP and PIM-DM is that PIM-DM works with whatever unicast protocol is being used. Also, PIM-DM does not

require any particular unicast routing protocol.

–

Sparse Mode is most useful in the following instances:

•

There are few receivers in a group. Switches send multicast trafﬁc only to the devices that request it.

Senders and receivers are separated by Local Area Network (LAN) links.

The type of trafﬁc is intermittent.

PIM-SM is optimized for environments where there are many multipoint data streams. Each data stream is sent to a relatively small

number of the LANs in the internetwork. For these types of groups, Reverse Path Forwarding techniques waste bandwidth. PIM-SM

works by deﬁning a rendezvous point. When a sender wants to send data, it ﬁrst sends to the rendezvous point. When a receiver

wants to receive data, it registers with the rendezvous point. Once the data stream begins to ﬂow from sender to rendezvous point to

receiver, the routers in the path will optimize the path automatically to remove any unnecessary hops. PIM-SM assumes that no hosts

want the multicast trafﬁc unless they speciﬁcally ask for it.

PIM is able to simultaneously support dense mode for some multipoint groups and sparse mode for others.

•

DVMRP: DVMRP is a routing protocol that supports multicast. Stemming from RIP and used in the Internet's Mbone (multicast backbone),

DVMRP allows for tunneling multicast messages within unicast packets. It also supports rate limiting and distribution control based on

destination address and is responsible for the following:

–

Routes multicast datagrams

Periodically floods multicast traffic (similar to PIM-DM)

Allows use of non-multicast aware edge devices

INTERNET GROUP MANAGEMENT PROTOCOL

Internet Group Management Protocol (IGMP) is a communications protocol used to manage the membership of multicast groups. IGMP is a

required protocol in the Endura network and is used by IP hosts and adjacent multicast routers to establish multicast group memberships.

The speciﬁcation that deﬁnes how to handle “unknown” multicast groups is not deﬁnitive. In this case, some vendors block multicast streams

that have no members, while other vendors will ﬂood this same trafﬁc. Flooding multicast streams that have no members can present a problem

in the Endura network because each video stream can be approximately 2 Mbps. In even a relatively small network, ﬂooding Endura trafﬁc can

signiﬁcantly reduce network performance and the overall performance of the Endura system.

Endura Network Design Considerations

The Endura network is based on switching and routing technologies. When planning an Endura network, you need to know and understand the

difference between the traditional “Core” and “Intelligent Edge” network topology design approach.

•

Traditional network design approach

The traditional network design topology is based on a central network core, which is responsible for all routing decisions. This approach

requires the use of high-performance and high-cost core network equipment. This approach will work if the speciﬁed core switch is capable

of managing all of the following:

–

Making all of the unicast routing decisions

Making all of the multicast routing decisions

Handling all Endura network traffic: video, audio, PTZ, and UPnP

Handling all other existing network traffic

This approach may meet your network design requirements. However this approach might not be as scalable as the intelligent edge design,

because the volume of network trafﬁc can easily consume the capacity of the core switch.

If network expansion is a future goal, then the intelligent edge design offers a scalable networking solution.

Intelligent edge design approach

•

The alternative to the traditional design is the intelligent edge design. This design is based on placing smart switches at the network edge,

which reduces the need for a centralized core to make all routing decisions. Instead of a single core switch managing all of the routing and

network trafﬁc decisions, in the intelligent edge design, processing is distributed across all managed switches. The intelligent edge design

allows the network to scale because managed switches can be easily added to the network without burdening a single core switch.

As compared to the traditional design, the intelligent edge design does not use the concept of a “core switch.”

Understanding the Endura Network Structure

The primary structure of an Endura network topology is organized into functional entities, which are called “blocks.” Grouping the functional

entities into individual blocks provide the following beneﬁts:

•

Blocks control and isolate trafﬁc.

Block design can be physical or logical.

Each block is separated by VLANs.

Blocks help determine network requirements.

The block concept makes it easy to understand and implement the Endura network design.

•

A Block: The A Block is functionally responsible for encoding, recording, and storage of the video streams entering the Endura network

(both live and playback video).

B Block: The B Block is functionally responsible for decoding and displaying the video streams, as well as providing the control and

conﬁguration of all Endura components.

Core Block: The Core Block is functionally responsible for Network layer 3 tasks, authentication and security, and interconnects the A and

B blocks.

C Block: The C Block includes the entire block structure: A, B, and Core.

VLANS

VLANs are an essential network topology requirement in the Endura network.

•

Each Endura block is separated by VLANs.

VLANs are groupings of switch ports creating different network segments for each group.

–

Switches using VLANs create the same division of the network into separate broadcast domains are also a more cost-effective

solution.

–

It is necessary to use a router when moving between VLANs.

•

VLANs reduce the size of the broadcast domain.

VLANs are used to managed and restrict Endura trafﬁc.

VLANs operate at layer 2 of the Open System Interconnection (OSI) model.

All VLANs should be assigned an IP address to support routing.

UPnP

Endura uses UPnP to enable easy and dynamic connectivity between devices on a network. Devices may dynamically add themselves to a

network without the need for user intervention or conﬁguration. UPnP also allows devices on the network to check in with each other

periodically. This means the user can know which devices are available at any one time. If a device goes off line, users can be notiﬁed so the

problem may be addressed quickly, with minimal down time.

UPnP trafﬁc stays isolated to VLANs because of Time-To-Live (TTL) settings. TTL determines how many network segments a packet can cross into

before it is discarded. TTL for UPnP packets is set to 1 so that the UPnP packets do not cross out of their originating block. TTL for video packets

is set much higher so that the video packets can traverse the entire network. For more information on TTL is used in the Endura network, refer to

Using TTL to Control Network Trafﬁc in Broadcast Domains on page 11.

ENDURA A BLOCK

The A Block is the most important design entity of the network. The A Block is functionally responsible for encoding, recording, and storage of

the video streams entering the Endura network (both live and playback video).

The A Block is summarized as follows:

•

Each A Block can support up to 48 Encoders and one NVR5100.

Each A Block is assigned to a speciﬁc VLAN.

The number of A Blocks is unlimited.

Each A Block has only one NVR5100 for recording of video streams from all Encoders in the A Block. Additional storage is provided by

SEB5000 storage expansion boxes.

Figure 1 shows the Endura components that comprise the A Block. The SEB5000 is shown directly connected to the NVR5100 using a patch

cable. If multiple SEB5000s are required, you can use a dedicated, Pelco-approved gigabit Ethernet switch to expand the video storage of the

NVR5100. For more information about connecting SEB5000s to the NVR5100, refer to Connecting the NVR5100 and SEB5000s on page 26 and

Connecting Multiple NVR5100s and SEB5000s on page 26.

BROADCAST DOMAINS AND VLANS

In a network, the logical area within which all devices can see each other’s broadcasts is referred to as a broadcast domain. Endura components

generate multicast trafﬁc, which in some cases can be treated like broadcast trafﬁc, depending on the switch. For this reason, it is important to

isolate these broadcasts and to create a separate broadcast domain for each Endura block on the network. The most efﬁcient approach is to use

VLANS to separate the broadcast domains (refer to Figure 2).

USING TTL TO CONTROL NETWORK TRAFFIC IN BROADCAST DOMAINS

In the Endura network, TTL is used to set the maximum amount of router hops that a packet is allowed to propagate through the network before

the packet is discarded. Using TTL provides an effective method to determine how many broadcast domains a given packet can traverse.

•

For Endura components (excluding the SM5000), the default TTL settings are as follows:

–

UPnP trafﬁc: The TTL is set to 1. In this case, each block is assigned to a specific VLAN, keeping UPnP traffic isolated within that block

(refer to Figure 3).

–

Video packets: The TTL is set to 3 so that the video packets can traverse the entire network.

•

For the SM5000 in the Core Block, the default TTL setting is 4. In this case, the SM5000 Locator broadcasts can traverse across

subnetworks to discover Endura components.

This approach ensures that two networking functions be efﬁciently accomplished:

•

Each NVR5100 only records video streams from encoders from which it sees in its block. The NVR5100 sends a query with a TTL of 1, which

means it will only discover devices on its VLAN.

•

Unnecessary trafﬁc is eliminated from traversing across the Core Block.

Figure 3 illustrates how the broadcast trafﬁc is localized to A Block 1 in broadcast domain 1. In this case, the broadcast trafﬁc from VLAN 1 never

traverses the network because TTL is decremented to 0 at the core switch and the packet is dropped.

ENDURA B BLOCK

The Endura B Block generally determines the bandwidth requirements for the network. The B Block is functionally responsible for decoding and

displaying the video streams, as well as providing the control and conﬁguration of all Endura components.

The B Block functionality is summarized as follows:

•

Based on permissions, can view and control any camera on entire system

Each B Block is assigned to a speciﬁc VLAN

The B Block can be replicated any number of times (limited only by network capacity)

ENDURA TRAFFIC SUMMARY DETAILS

This section provides information that allows you to calculate the bandwidth requirements for the Endura network. The Endura trafﬁc details are

summarized as follows:

•

Maximum video stream from an NET5301T encoder is 5.0 Mbps plus overhead:

–

Up to 3.0 Mbps total for both multicast live streams

•

Up to 2 Mbps for stream 1 (4CIF)

Up to 1 Mbps for stream 2 (CIF)

–

Up to 2.0 Mbps for unicast recording stream

For information on calculating the bandwidth, refer to Calculating Bandwidth and Storage Requirements on page 13.

•

5.5 Mbps total with audio and data.

Network utilization should always be ﬁgured for the worst-case scenario. For information on calculating the worse-case bandwidth, refer to

Calculating Bandwidth and Storage Requirements on page 13.

•

Playback is not a stream, but a “burst” of data.

Each NVR5100 has a 100 Mbps cap on playback data:

–

The NVR5100 will use as much of 100 Mbps bandwidth as necessary to transmit the requested clip data.

The NVR5100 will divide that 100 Mbps up among multiple playback requests if necessary.

•

NVR5100 playback is unicast.

Constant and frequent requests for playback video must be included when determining worse-case bandwidth.

NOTES:

•

Live video trafﬁc is only steamed across the network when requested by a view station.

Throughput needs to be calculated at various points on the network, depending on how many cameras are going to be viewed and at

what size.

C1640M-B (3/06)

CALCULATING BANDWIDTH AND STORAGE REQUIREMENTS

You must ensure that the B and C blocks are able to handle the worse-case bandwidth (B ) requirements. The following examples describe how

to calculate the worse-case bandwidth based on the playback video stream.

NOTE: Playback steams are used for calculating worse-case bandwidth requirements because each video stream is played back at the same

rate that it was recorded, no matter in what layout mode the video stream is being displayed.

In contrast, when viewing live video, the Endura WS5050, VCD5000, and NET5301R use EnduraView to select the appropriate video stream

automatically based on the layout mode.

•

WS5050: The WS5050 pulls the highest value stream in either the single camera or quad layout mode.

VCD5000: The VCD5000 pulls the lowest stream in quad layout mode.

WS5050 or VCD5000: The WS5050 or VCD5000 pulls the lowest value stream in the 9- or 16-camera layout mode.

NET5301R Encoder:

–

The NET5301R pulls the highest value stream in the single layout mode.

The NET5301R pulls the lowest value stream in the quad layout mode.

The following examples demonstrate that the playback video mode requires more bandwidth than does the live video mode. Typical applications

do not require displaying the maximum amount of simultaneous playback streams. A more realistic application might require more live video

streams are displayed than playback video streams. For this reason both playback and live video calculations are shown to aid in calculating

bandwidth.

To ensure that your network resources are more than adequate to support the Endura system, it is recommended that you use the bit rate

applicable for the playback video mode when calculating worse-case bandwidth requirements.

•

For information on calculating bandwidth for the playback video mode, refer to Examples of Worse-Case Bandwidth Calculation in Playback

Mode on page 20.

•

For information on calculating bandwidth for the live video mode, refer to Examples of Worse-Case Bandwidth Calculation in Live Video

Mode on page 21.

The worse-case bandwidth, B , requirements for live and playback video is given by the equation:

= B + O

where:

= Bandwidth and is given by the equation: B = N x B

O = Overhead and is given by the equation O = 25% x B

W .

N = Number of streams.

B = Bit rate

The above equations are general and assume that all playback streams are of the same quality. For information about B values, refer to NTSC

Frame Rates on page 14 and PAL Frame Rates on page 17.

Examples of Worse-Case Bandwidth Calculation in Playback Mode

NOTE: For the examples below, assume that all recorded video is at 4CIF (2 Mbps) at 30 IPS:

•

In this case, if playback video is displayed in the single layout mode, then the display rate is at 30 IPS.

However, if playback video is displayed in 4 x 4 layout mode, the display rate is at 2 IPS. In this case, the bandwidth is still 2 Mbps.

Example 1: WS5050 Endura Workstation—Playback Video Stream

Each WS5050 can display 16 simultaneous playback streams.

To calculate the worse-case bandwidth for the WS5050:

1. Find the bandwidth.

= N x B = 16 x 2 Mbps = 32 Mbps

2. Find the overhead.

O = 25% x B = 16 x 2 Mbps x 25% = 8 Mbps

3. Find the worse-case bandwidth.

= (N x B ) + O = 32 Mbps + 8 Mbps = 40 Mbps

EXAMPLES OF ENDURA NETWORK DESIGNS

This section describes various Endura network conﬁgurations that are scalable and allow you to structure the network for the current as well as

future application requirements. Since Endura is a system comprised of high bandwidth IP products, there are speciﬁc networking approaches

that must be observed.

•

If Endura is going to be integrated into an existing network, the existing network must meet the requirements as listed in Endura Network

Design Considerations on page 8.

•

The Endura Block design approach must be implemented to manage Endura network trafﬁc efﬁciently.

There are two types of Endura network designs:

•

Unmanaged

Managed

UNMANAGED NETWORK CONFIGURATION

The unmanaged Endura network only supports viewing of live video. As shown in Figure 8, an unmanaged Endura network can include NET5301T

encoders and NET5301R decoders, a WS5050 Endura Workstation, VCD5000 video console display, and a switch. The unmanaged network can

support up to 16 cameras.

A unmanaged Endura network does not include the SM5000 system manager or NVR5100. In this case, there is no recording or security

functionality. The WS5050 provides limited system manager functionality and can only handle up to 16 cameras on a system. If the security

network application requires more than 16 cameras or an NVR5100, then the network must be designed as a managed network requiring a

SM5000 system manager.

MANAGED NETWORK CONFIGURATION

The managed Endura network supports viewing of live and playback video, recording, and security. As shown in Figure 9, a managed Endura

network includes the full assortment of Endura components: NET5301Ts, NET5301Rs, WS5050s, VCD5000s, NVR5100s, the SM5000, and

switches.

The managed Endura network is designed in a four-part block structure (A Block, B Block, C Block, and Core Block). For more information about

the block design concept, refer to Endura C Block on page 23.

•

A Block (VLAN 2): This is where all video streams enter the network (both live and playback) and where video is recorded by the

NVR5100s and stored in SEB5000s. Each A Block can contain no more than 48 NET5301Ts and one NVR5100. The NVR5100 in each

respective A Block records video steams from the Encoders in the same A Block.

•

B Block (VLAN 4): This is where all video viewing takes place, and VCD5000s, NET5301Rs, and WS5050s are connected to the Endura

network.

•

Core Block (VLAN 3): This is where the SM5000 resides. The Endura Core Block interconnects the A and B Blocks.

C Block: The entire structure including A Blocks, B Blocks and the Core Block is referred to as the C Block.

For more information about the block design concept, refer to Endura Network Design Considerations on page 8.

You can have multiple A Blocks in an Endura network.

•

The number of cameras and amount of storage needed for the video security network determines how many SEB5000s are needed in an

A Block.

•

As with A Blocks, there can be multiple B Blocks in the network, but as many as the network can support. Generally, the B Block uses the

most bandwidth across the network.

•

The SM5000 is connected to the core switch and resides in the Core Block.

The Core Block implements network connectivity between all Endura components to comprise the basic Endura network.

Connecting the NVR5100 and SEB5000s

The SEB5000 storage expansion box can be connected to the NVR5100 in one of two ways:

•

A patch cable is used to connect a single SEB5000 directly to an NVR5100 (refer to Figure 10). The NVR5100 and SEB5000 Ethernet port is

autosensing.

Connecting Multiple NVR5100s and SEB5000s

In a large system it is possible to use one storage switch to network multiple NVR5100 and SEB5000 combinations. If multiple NVR5100s are

used in the network, Pelco requires that VLANs be conﬁgured on the storage switches because it is important to segment communication so that

each NVR5100 only communicates with the SEB5000s to which the NVR5100 is assigned.

Figure 12 shows an example of how to segment the network using VLANs.

•

NVR5100 #1 resides in VLAN 1 and NVR5100 #2 resides in VLAN 2.

SEB5000 #1 resides in VLAN 1 and SEB5000 #2 and SEB5000 #3 reside in VLAN 2.

In this case, NVR5100 #1 stores video streams on SEB5000 #1 and NVR5100 #2 stores video streams on SEB5000 #2 and SEB5000 #3.

The segmenting of devices by VLANs prevents NVR5100 #1 from communicating with SEB5000 #2 or #3. Likewise, NVR5100 #2 is prevented

from communicating with SEB5000 #1.

This section provides an example of how to conﬁgure an HP 5300 series chassis switch for an Endura Network. The information is this section is

only an example of how to conﬁgure an HP 5300 series chassis switch. Although this example is typical, other network conﬁgurations can support

Endura. For more information about advanced conﬁgurations, refer to HP Advanced Trafﬁc Management Guide at www.hp.com/go/procurve.

Figure 13. Example Endura Network and HP 5304 Switch Conﬁguration

The network diagram above will be used throughout this document to demonstrate how to set up a basic Endura system.

The HP 5300 series chassis switches have multiple slots available to insert a variety of modules as follows:

•

ProCurve Switch xl 16-port 10/100/1000 Module (J4907A)

ProCurve Switch xl 10/100-TX PoE Module (J8161A)

ProCurve Switch xl 10/100-TX Module (J4820A)

ProCurve Switch xl 100/1000-T Module (J4821A)

ProCurve Switch xl Mini-GBIC Module (J4878A)

ProCurve Switch xl 100-FX MTRJ Module (J4852A)

For the purposes of discussion in this section, assume the following:

•

Switch A has one 16-Port 10/100/1000 Module in slot A (Ports A1-A16).

Switch B has one 16-Port 10/100/1000 Module in slot B (Ports B1-B16).

The switches are in their default state.

The command ‘erase startup-conﬁg’ was issued before any conﬁguration.

Ports A16 and B16 are used to link the two switches together.

NOTE: Use the serial cable that is supplied during all conﬁgurations. While this is not necessary, it allows you to view messages during the

bootstrap process on the switch, which might be helpful if you have to perform troubleshooting.

The following sections provide a procedure conﬁguring switch A and B using RIPv2 as a routing protocol because RIPv2 is easier to conﬁgure.

However, static routes or OSPF are alternative methods. Also, IP helper addresses are setup on VLAN 1, which is only required if a DHCP client

resides on this VLAN. No device other than a switch should reside on VLAN 1 because there are multiple gateways on VLAN 1.

Appendix B: WAN Conﬁguration Example

This appendix provides a sample conﬁguration for multicasting over a generic routing encapsulation (GRE) tunnel as an example of how to

conﬁgure an Endura network using WAN connectivity. Much of the information in this appendix is derived from the online document titled

Multicasting Over a GRE Tunnel, published by Cisco Systems^®. To view this document, go to or click http://www.cisco.com/en/US/tech/tk828/

technologies_conﬁguration_example09186a00801a5aa2.shtml.

In an Endura application scenario, where you want to extend an existing Endura network across a network that does not support multicast, it is

recommended that you conﬁgure a GRE tunnel to send multicast trafﬁc between routers. In this case, the GRE tunnel is required because the

multicast source and receiver are separated by an IP cloud that is not conﬁgured to support IP multicast trafﬁc. In such network scenarios,

conﬁguring a tunnel across an IP cloud with PIM will allow multicast packets to be exchanged between the source and receiver.

This appendix describes the conﬁguration, veriﬁcation, and related issues pertaining to multicasting over a GRE tunnel. The information

presented in this appendix was created from devices in a speciﬁc lab environment. All of the devices used in this appendix started with a cleared

(default) conﬁguration. If you are working in a live network, ensure that you understand the potential impact of any command before using it.

NETWORK CONFIGURATION OVERVIEW

As shown in Figure 15, the multicast source (10.1.1.1) is connected to R102 and is conﬁgured for multicast group 239.1.1.20. The multicast

receiver (10.2.2.3) is connected to R104 and is conﬁgured to receive multicast packets for group 239.1.1.20. Separating R102 and R104 is an

IP cloud, which is not conﬁgured for multicast routing.

Figure 15. Sample Endura Network Over a WAN

A tunnel is conﬁgured between R102 to R104 sourced with their loopback interfaces. The ip pim sparse-dense mode command is conﬁgured on

tunnel interfaces and multicast-routing is enabled on R102 and R104. Sparse-dense mode conﬁguration on the tunnel interfaces allows sparse-

mode or dense-mode packets to be forwarded over the tunnel depending on rendezvous point (RP) conﬁguration for the group.

•

For dense mode: With PIM dense mode conﬁgured over the tunnel, an ip mroute 10.1.1.0 255.255.255.0 tunnel 0 command is conﬁgured

on R104 to ensure a successful RPF for multicast source address 10.1.1.1. Incoming (10.1.1.1, 239.1.1.20) multicast packets over Tunnel0

(Tu0) are checked for Reverse Path Forwarding (RPF) using this mroute statement. After a successful check, the multicast packets are

forwarded to outgoing interface list (OIL) interfaces.

•

For sparse mode: With PIM sparse mode conﬁgured over the tunnel, ensure that the following points are addressed:

–

For a successful RPF verification of multicast traffic flowing over the shared tree (*,G) from RP, an ip mroute rp-address nexthop

command needs to be configured for the RP address, pointing to the tunnel interface.

Assuming R102 to be the RP (RP address 2.2.2.2) in this case, the mroute would be the ip mroute 2.2.2.2 255.255.255.255 tunnel 0

command, which ensures a successful RPF check for trafﬁc ﬂowing over the shared tree.

For a successful RPF verification of multicast (S,G) traffic flowing over the Shortest Path Tree (SPT), an ip mroute source-address

nexthop command needs to be configured for the multicast source, pointing to the tunnel interface.

In this case, when SPT trafﬁc is ﬂowing over tunnel interface an ip mroute 10.1.1.0 255.255.255.0 tunnel 0 command is conﬁgured on

R104 to ensure a successful RPF veriﬁcation for incoming (10.1.1.1, 239.1.1.20) multicast packets over the Tu0 interface.

The sample conﬁguration ﬁles for R102 and R104 are described in the following sections:

VERIFYING THE CONFIGURATION

Complete the following steps to verify your conﬁguration:

1. Use the show ip igmp groups command to verify that the receiver has sent its IGMP join membership request for group 239.1.1.20 to R104.

r104# show ip igmp groups

2. Use the show ip mroute group-address command to display that when the source 10.1.1.1 starts multicasting packets for the group

239.1.1.20, R102 installs the (*,239.1.1.20) and (10.1.1.1, 239.1.1.20) entries in the R102 mroute table, as shown below.

3. Use the show ip mroute group-address command to verify that R104 has the (*,239.1.1.20) and (10.1.1.1, 239.1.1.20) entries while it is

forwarding multicast packets for group 239.1.1.20 sourced from 10.1.1.1, as shown below.

Incoming interface: Tunnel0, RPF nbr 192.168.24.1, Mroute

Outgoing interface list:

Ethernet0/0, Forward/Sparse-Dense, 00:01:13/00:00:00

NOTE: In (10.1.1.1, 239.1.1.20), the incoming interface is Tunnel0 and the RPF neighbor is 192.168.24.1—the Tunnel head end on R102.

The RPF veriﬁcation is done based on the Mroute conﬁgured on R104, and the multicast packets are pushed out to the OIL to the receiver

connected on the Ethernet 0/0 interface.

4. Use the show ip rpf ip-address command to perform an RPF veriﬁcation for packets sourced from 10.1.1.1. The following example conﬁrms

that RPF for 10.1.1.1 is via Tunnel 0, on which we are receiving the multicast (S,G) packets.

r104> show ip rpf 10.1.1.1

RPF information for ? (10.1.1.1)

RPF interface: Tunnel0

RPF neighbor: ? (192.168.24.1)

RPF route/mask: 10.1.1.1/24

RPF type: static

RPF recursion count: 0

TROUBLESHOOTING

If your multicast over GRE tunnel is not working, one of the following could be the cause:

•

Tunnel not UP/UP: The tunnel source and destination do not match on each end of the tunnel. For example, if the tunnel destination on

R102 was changed to the IP address 10.2.2.2 instead of 2.2.2.2 while the conﬁguration on R104 remained the same, the tunnel would not

come up. To verify the status of the tunnel, use the show interface tunnel 0 command.

•

RPF Failure: Use the show ip mroute count command to verify that the multicast packets are dropped because of RPF failure. A sample

output of the show ip mroute count command and its increasing counters for RPF failure is shown in bold below:

r104# show ip mroute count

IP Multicast Statistics

3 routes using 1642 bytes of memory

2 groups, 0.50 average sources per group

•

Forwarding Counts: Pkt Count/Pkts per second/Avg Pkt Size/Kilobits per second

Other counts: Total/RPF failed/Other drops(OIF-null, rate-limit etc)

Group: 224.0.1.40, Source count: 0, Packets forwarded: 0, Packets received: 0

Group: 239.1.1.20, Source count: 1, Packets forwarded: 11, Packets received: 45

Source: 10.1.1.1/32, Forwarding: 11/0/100/0, Other: 25/14/0

!--- After some time, the show ip mroute count command is issued again.

!--- You can see the RPF failed counter increasing:

r104# show ip mroute count

IP Multicast Statistics

3 routes using 1642 bytes of memory

2 groups, 0.50 average sources per group

Forwarding Counts: Pkt Count/Pkts per second/Avg Pkt Size/Kilobits per second

Other counts: Total/RPF failed/Other drops(OIF-null, rate-limit etc)

Group: 224.0.1.40, Source count: 0, Packets forwarded: 0, Packets received: 0

Group: 239.1.1.20, Source count: 1, Packets forwarded: 11, Packets received: 50

Source: 10.1.1.1/32, Forwarding: 11/0/100/0, Other: 30/19/0

r104#

Use the show ip rpf source command to ensure that the RPF interface is the same as that on which the source multicast packets are

received—Tunnel 0 in this example. For more information on RPF failures, go to or click http://www.cisco.com/warp/public/105/

mcastguide0.html to access the IP Multicast Troubleshooting Guide.

•

PIM Neighbors: Router R102 is not forwarding over the Tunnel0 interface because it is not seeing a PM neighbor R104. You can use the

show ip pim neighbor command on R102 to show the neighbor R104 over the tunnel. You can also use the show ip pim int command to

show that there is a neighbor. Verify that the interface level ip pim sparse-dense-mode command is conﬁgured on both ends of the tunnel

and that IP multicast-routing is enabled.
